The TangoDown Flip Grip is an innovative grip for the AR-15 which allows the user to change the grip angle in seconds. Installed in the traditional configuration, the Flip Grip offers a standard 24 degree grip angle. By pulling down on the bottom portion of the grip and rotating 180 degrees, the Flip Grip now offers a true vertical grip. A positive locking notch ensures that the grip will never rotate in the users hand and the textured grip allows for positive retention of the weapon. The tough polymer construction and stainless steel hardware ensures the grip will stand up to hard use and all conditions.
